Siglent SDS1052DL Digital Storage Oscilloscope with Frequency Counter, 50MHz, 7'' TFT-LCD Display

Very good scope for the money. I've used it extensively since receiving it and it has more than met my needs.I did have one little issue where the device locked up during power-up. I called Siglent America and the engineer told me to cycle the MATH button at one second intervals while it boots. This cleared the condition and all is now normal. This is a common problem when you have the scope doing advanced functions prior to powering it down and then power back up with the previous signals removed. The MATH reset is undocumented, so hopefully this tip will help others.If you connect this scope to your computer using the USB cable, it takes a little work to get all the National Instruments drivers running, but once you get it working, forget about using a flash drive for saving screenshots. You can dump right to the computer and save the images directly which is most helpful when discussing a project on a forum or such. This feature is certainly optional, but it's a great time saver if you take the initial time to get it all set up.Some may complain this scope isn't fast enough, the screen resolution is too small, the fan is noisy, it only has two channels, etc. If you want to fix all that, sure buy a high-end scope--the sky is the limit. If you need something inexpensive that you can put to work right now, this scope fits the bill in most cases. If you're a novice, this is a great starter scope and you will spend days learning about what all it can do. If you come from the background of only using an analog scope, you'll flip over the things this scope can do that were nearly impossible with the old analog scope. You'll be able to actually see for the first time and take measurements so painlessly it's scary. And no more taking pictures of the screen with a camera to show others.Highly recommend. I'm giving it four stars because it's not perfect. It's really good, well above average. The money you'll save buying this you can use to buy parts so you'll have something to test with. :-)

I had bought this as a home and hobby scope so I could do most of my homework at.. well, not the EE labs on campus. Being a student, I am no expert at using quality lab equipment, but I can say that compared to the ~slightly~ more expensive Rigol units I use on campus it has it's ups and downs.PROS (compared with Rigol DSE110...)- The screen is large, one of my favorite features compared to what I use at school- Has all the features of the Rigol, and the Print button works as a direct screenshot to a USB drive which I like, a lot.CONS- The wave forms are not exactly stable, they jump around much more than the scopes at the U.- The cursor function is quite as good as the scopes at the U, for example: If I set Cursor A and then Cursor B there is no way to move them both at the same time. I have to move one at a time. To do this I need to directly access the menu. Whereas, on the Rigol units, a press down on the Adjustment knob makes the switch from Cursor A -> Cursor B -> Both. This seems like such an easy feature to implement it's frustrating not to have it handy at home.Again, my skills at using O-scopes is rudimentary. All in all, this is a good scope for the money, and if I had to recommend a scope to someone in the under 300$ range I would definitely recommend this one.

My Tek finally died - the high voltage section was fried. I went on Amazon to see what was available. I service audio equipment as a side line. After reading the specifications of the Siglent scope I decided to buy it. It is rated as a 50 MHz scope - but I have no trouble displaying a 100 MHz signal. On feature which I did not see listed is it has a frequency counter. The frequency counter is dead on and is actually more sensitive than my TEK 5316. My signal generator only goes up to 108 MHz and it only takes about 15 Millivolts of RF for the counter to lock in.One other thing about this scope is when I use it with a sweep generator and use channel 2 as the horizontal reference, there is no drift in the display. With both analog scoped that I had owned, the scope would need a warmup time of 10 minutes or so to be stable. There is no warm up time needed with this Siglent.If you are looking for a general purpose scope the Siglent is excellent. I am 100% happy with it. There is only one thing about it that I had to change in my equipment stack up. On the top of my stack was the frequency counter, then the scope, then the RF generator and finally the distortion analyzer. Well with the small size of the Siglent I could not stack the frequency counter on it. So I took my 5316 out of service because my new scope is actually a better frequency counter.The TFT display is excellent. There is a on screen menu display that will let you quickly set up the scope. The scope comes with a set up guide, a CD, two very nice probes and a USB cable. It is a compact unit that is only

(Edit March 25, 2016 - The review below, which originally gave this product 4 stars, points out that the scope arrived with one probe defective. I could have, at the time, returned it to Amazon for a refund, but I tried to work with the seller and the manufacturer to get this one small defect corrected without such drastic measures. I patiently waited while the seller celebrated Chinese New Year, and for several weeks after. Now that the return eligibility period for Amazon is expired, the manufacturer does not reply to e-mails. If you choose to buy this product, do so with the knowledge that you have NO warranty, NO after-sales support, and if there is the slightest hint of a problem, return it at once!)This scope has many positive features. It worked well right out of the box and is an affordable piece of test equipment. I am a recently retired electronics technologist who has spent a lifetime working on $10,000+ oscilloscopes, so it is all too easy for me to be critical of some of the less than professional qualities of this item. Nevertheless, I do recognize that the manufacturer has tried hard to provide the best quality possible within a hobbyist's price range.Positive features include;- Calibrated and accurate out of the box.- Intuitive control layout, not entirely different from tube based scopes I worked on 40 years ago. No re-inventing of the wheel.- Quality buttons and knobs which give a solid, professional feel to scope operation.- Well packed, and a generally attractive appearance.- Smooth operation based on a well-designed hierarchy of menus, and a large, bright and clear display.Less positive;- One probe was defective on arrival. The supplier (Banff Sky) is working to get it replaced, but they are running up against the Chinese New Year holiday - the country is just about closed (as I know well from my inability to buy components on eBay.) Assuming that all goes well with the replacement once they are back from holiday, I will not consider this too serious a flaw, but it is true that the probes are a bit cheaper in design than the scope itself - I will likely end up replacing them either way.- The scope lacks an X-Y setting on the time base, making Lissajous pattern measurements impossible.- The auto-setup button is right under the run-stop button. As run/stop is often pressed while holding a probe on a circuit and looking out of the corner of one's eye, it's all too easy to hit the auto-setup by mistake and mess up the carefully adjusted settings. In truth though, the far more expensive Tektronix 246x series had the same flaw. I hated this on those models too.

Cheap and perfect! I don't do anything about 50 MHz, so this is perfect!There was some problems with shipping (it was held in customs for inspection for a few weeks), but it eventually arrived. Works out of box. Simple to use: one screen testing and calibration, built in 1 kHz square wave for testing, and the probes are of decent quality too. I have one at home on my workbench, and one at work too!

Good product for quality/price.

A great all around small oscilloscope, Hope to have many years of service for this hobbyist.

It's my first oscilloscope and I didn't have a big budget so I chose it. It works very well and does all I need. The price was good for what it can do and for the general build quality. Also, it is light weight so it can be easily moved.
